MODELING AND SIMULATION OF SWITCHED SYSTEMS: A DYNAMIC STRUCTURE APPROACH

Submitting Author: Prof. Fernando Barros

Abstract:
We present a new modeling approach to the representation of switched systems based on hybrid flow dynamic structure models. This solution permits to exploit the incremental changes between two models in contrast to more traditional approaches that involve the exchange of complete models. The proposed solution is based on the Heterogeneous Flow System Specification (HFSS), a formalism aimed to represent hierarchical hybrid systems with a time-varying structure. The approach is exemplified by modeling an electrical switched system. Numerical simulation results of this system illustrate the ability of the HFSS formalism to represent multi-rate numerical methods.
